Northern Rockhopper penguins are a group of crested penguins known for their distinctive yellow and black spiky feathers on their heads, red eyes, and strong, pink-webbed feet. They belong to the genus Eudyptes and are named for their habit of hopping over rocks and crevices in their rugged, rocky island habitats.

The Northern Rockhopper Penguin (Eudyptes moseleyi) inhabits Islands in the South Atlantic Ocean and the Indian Ocean, including Tristan da Cunha and Gough Island.

Like many penguins, they have a classic black-and-white coloration, with a white belly and a black back, head, and wings.
